Nabi makes a giant android touchscreen which I would like to use for a unity3d project. It’s called the big tab 24. It comes with kit kat 4.4. and on top runs it’s own OS for kids.

I need some sound features that exist only in lollipop 5.1 for my project.
How would I update a device like this to lollipop 5.1?
Would I need to root it? I am a complete newbie at android having previously only worked on IOS.
